It may not have ripped apart the very top of the general classification battle but that stage delivered on many of its promises.
It also proves that short, sharp stages may be the way forward to bring a bit more excitement back to this sport.
A French winner on Bastille Day a fitting end. Well done Warren Barguil.
So Fabio Aru keeps yellow but his rivals will go again.
The report of today's stage is building here.
For now, farewell.
Riders keep streaming over the finish line in Foix.
A big group have just wheeled in 15 minutes behind the leaders. The cut-off is expected to be at around 30 minutes so even if there are groups left out on the road, they shouldn't be in danger of missing the time limit.
Warren Barguil makes it the fourth French stage win this Tour after Arnaud Demare, Lilian Calmejane and Romain Bardet.
A moment to redeem that heartbreaking finish on stage nine - when Barguil raised his hands in celebration, was taken to the winner's enclosure, only then to find out Rigoberto Uran had pipped him on the line.
No changes to the top four on general classification but a bit of movement below:
The last French stage winner on Bastille Day was David Moncoutie in 2005.
What a way for Warren Barguil to end a 12-year wait.
The Sunweb rider went off in search of mountains classification points to cement his lead in that competition but had enough power to see off grand tour winners Alberto Contador and Nairo Quitana in the finale.
The top three on stage 13:
That meant Team Sky's Mikel Landa finished fourth so didn't pick up any bonus seconds. However, he's moved himself up to fifth on general classification and is a legitimate threat along with team leader Chris Froome now.
Here they come - no late drama amongst the GC favourites as Fabio Aru retains the yellow jersey, rolling over the line alongside Chris Froome, Romain Bardet and Rigoberto Uran.
Dan Martin and Simon Yates will sprint for fifth and sixth on the stage - Yates gets it on the line and a few precious seconds.
Yellow jersey group on their tails...
Warren Barguil gets it!
Alberto Contador has a dig but is quickly followed and it comes down to the final drag.
None of these riders renowned for their sprint but Barguil has the most power remaining to win the stage.
A French winner on Bastille Day. Chapeau!
Get ready for a climber's sprint...
Into the final kilometre in Foix.
Four riders to contend for the stage - Contador, Quintana, Barguil and Landa.
Front four lead by 2'02''
So into the final 2km to go to Foix. It doesn't look like Landa has enough road to take yellow now but a stage win is still on the cards.
Quintana, Barguil and Contador will have something to say about that, though.
Behind, Simon Yates has attacked and joined Dan Martin.
The rest of the favourites holding steady now. A truce for the day?
Chris Froome puts the hammer down again but is instantly matched by his rivals.
Not sure why he's doing that - Mikel Landa is out front and in contention to take yellow.
Surely just sit back and force Fabio Aru to do the chasing.
Front four lead by 2'09''
Team Sky's Mikel Landa is still firmly in contention to take the yellow jersey from Fabio Aru.
He needs two minutes 55 seconds to do it - although if he wins the stage, he'll get 10 bonus seconds so could just need two minutes 45 seconds.
If the following group continue to attack and counter with little fluidity, the leading group could stretch their advantage.
Contador, Landa, Quintana and Barguil lead by 1'52''
The front group reach 6km to go and still have a sizeable lead.
Dan Martin has attacked behind. Smart move by the Quick-Step rider - he's not a threat to the top three on GC right now and so the likes of Fabio Aru and Chris Froome are happy to let him go. For now.
Yep, sure enough, Chris Froome and Michal Kwiatkowski have a quick word, go to the front and reel Rigoberto Uran back in.
Dan Martin goes again down the right...
The rest of the yellow jersey group have lost sight of Rigoberto Uran.
A tremendous effort from the Colombian.
Surely the rest have to counter soon?
Rigoberto Uran has gone and opened up a sizeable gap on the descent.
The Colombian is just 35 seconds behind yellow jersey Fabio Aru in the overall standings.
Front four lead by 1'59''
Quintana could be putting himself back in contention for a podium if this leading group maintain a two-minute advantage.
He's four minutes one second behind Fabio Aru and has looked knackered at times in this Tour - but can this inspire him going forward?
Front four lead by 1'58''
The leading group of Quintana, Contador, Landa and Barguil are about to come off the mountain road and back onto a main road, where it does flatten out a bit more after this lengthy descent.
Then they will time trial to the finish in Foix, no doubt with a bit of cat-and-mouse along the way as each look to win the stage.
